Research Interests: My research interests concentrate on comparative, adaptive mechanisms of reproductive processes. I am intrigued by the vast array of reproductive strategies which all have evolved to one end: the production of young. Investigations of morphology, physiology (especially endocrinology) and behavior of a wide variety of animals provide data on conserved versus unique features. Results from captive studies have particular application to conservation programs of captive breeding and reintroductions.
